BACKGROUND

The present invention generally relates to increasing the data capacity of a network connection between two devices. In particular, the invention relates to methods and other accommodations for increasing the data capacity of a network connection based on the network address to which or from which data is requested.

As more and more computer applications require multimedia files to operate, computer networks require more bandwidth to deliver large files from servers to workstations. Typically in a computer network, a network device will allocate a specific amount of bandwidth to individual workstations on the network. However, at any given time one workstation may not use any bandwidth, while other computers require more bandwidth than they are allocated. Because of this non dynamic allocation, some network users experience slow downloading and uploading of files.

For multimedia applications, this results in delays in video and audio signals, static on the screen, and the freezing of images. Additionally, for file transfers a slow network connection can increase the amount of time required to upload files wasting time and resources. If the problem becomes critical, the service provider may receive calls to their customer service center or lose customers all together due to slow network performance.

FIG. 4A depicts a schematic representing the operation of the bandwidth negotiation system 100 consistent with the present invention. First, the multiplexing unit 106 receives a message or request from at least one end user device 102 via at least one of the plurality of network line I/O devices 214 (Step 402). Next, the message or request is forwarded to the analyzing unit 110 (Step 404). The network I/O device 308 on the analyzing unit 110 receives the message from the multiplexing unit 106 and the data inspection software 306, running on the analyzing unit 110 memory 304, removes data from the message or request (Step 406). The removed data is then transmitted to the content storage unit 112 for further analysis (Step (408).

The content comparator software 314 running on the content storage unit 112 memory 312 compares the data received from the analyzing unit 110 with data stored in the content library 316. If no match is found in the content library 316, the process stops. If a match is found, a message is sent from the content storage unit 112 to the multiplexing unit 106 instructing the port control software 206 to increase the data capacity of the communication connection with the end user device 102 (Step 412). The network I/O device 208 on the multiplexing unit 106 receives and forwards the instructions from the content storage unit 112 to the port control software 206 which increases the data capacity of the communication connection between the end user device and the network data unit 116 via the network line I/O device 210 in communication with the appropriate end user device 102 (Step 414). Simultaneously, the content storage unit 112 sends the extracted data to the advertisement unit 114 (Step 416).

The advertisement selection software 324 running on the memory 322 of the advertisement unit 114 retrieves an advertising message from the advertisement library 326 based on the data received from the content storage unit 112 (Step 418). The advertisement unit 114 sends the advertisement message to the multiplexing unit 106 which then sends the message to the end user device 102 which made the request (Step 420). Once the transmission of files between the end user device 102 and the network data unit 116 is completed, the port control software 206 returns the network line I/O device 210 to a lower data capacity (Step 424).

In one illustrative embodiment consistent with the present invention, one of the end user devices 102 sends a request, via the network line 104, to download a file from a network data unit 116 located on the communication network 108. The multiplexing unit 106 receives the request via the network line I/O device 210 in communication with an end user device 102. The port control software 206 on the multiplexing unit 106 receives the request and transmits the request to the analyzing unit 110 via the communications network 108. The data inspection software 306 on the analyzing unit 110 removes the end user device 102 network address and the network address of the network data unit 116. The data inspection software 306 transmits the network address of the network data unit 116 to the content storage unit 112 via the communication network 108.

The content comparator software 314 on the content storage unit 112 queries the content library 316 to determine if the network address of the network data unit 116 resides in the content library 316. If the network address of the network data unit 116 resides in the content library 316, the content comparator software 314 transmits the network address of the network data unit 116 to the advertising unit 114.

The advertising selection software 324 on the advertising unit 114 queries the advertising library 326 for an advertisement associated with the network address of the network data unit 116. When an advertisement is returned from the advertisement library 326, the advertisement selection software 324 requests the end user device's 102 network address from the analyzing unit 110. The advertisement selection software 324 then sends the advertisement to the multiplexing unit 106 which transmits the advertisement to the end user device 102 via the network line 104. Once the end user device 102 receives the advertisement, the end user device 102 presents the advertisement to the display output 216 which is effective to display the advertisement on the display unit 218.

The content storage unit 112 is configured to send a message to the multiplexing unit 106 to maximize the data capacity of the network line I/O device 210 in communication with the end user device 102. After the data capacity is increased, the multiplexer forwards the request from the end user device 102 to the network data unit 116 via the communication network 108. Once the data transmission between the end user device 102 and the network data unit 116 is completed, the port control software 206 on the multiplexing unit 106 lowers the data capacity of the network line I/O device 210.

FIG. 4B depicts a schematic representing the operation of the content comparator software 314. First, the analyzing unit 110 extracts the network address of the network data unit 116 from a message received from an end user device 102 (Step 426). Next, the analyzing unit 110 sends the network address of the network data unit 116 to the content storage unit 112 (Step 428). The content comparator software 314 on the content storage unit 112 queries the content library 316 to determine if the network address of the network data unit 116 resides in the content library 316 (Step 432). If the network address of the network data unit 116 does not reside in the content library 316, the process stops. If the network address of network data unit 116 resides in the content library 316, the content comparator software 314 transmits the network address of the network data unit 116 to the advertising unit 114.

FIG. 4C depicts a schematic representing the operation of the advertising selection software 324. First, the advertising unit 114 receives the network address of the network data unit 116 network address from the content storage unit 112 (Step 436). Next, the advertising unit 114 requests the network address of the end user device 102 from the analyzing unit (Step 440). The advertisement selection software 324 then queries the advertising library 326 for an advertisement message associated with the network address of the network data unit 116 (Step 442). If no advertisement is associated with the network address of the network data unit 116, the process stops. If a advertisement is associated with the network address of the network data unit 116, the advertisement selection software 324 sends the associated advertisement message to the end user device 102 via the multiplexing unit 106 (Step 444). The end user device 102 receives the advertisement message and presents the advertisement message to the display output 218. The advertisement message may include, but not be limited to, a flash file, a graphical interface panel, a web page, a computer graphic, a audio message, a video file, or any other multi-media file executable from an end user device 102.

Various embodiments of the present invention operate to increasing the data capacity of a network connection to its maximum level based on the address of a network data unit requesting data, problems with slow file downloading can be avoided. In addition, the quality of multimedia files sent to and from the network data unit and the end user device can be greatly improved. Also, in various embodiments of the present invention, preferred network data units may be given priority over other network data units improving customer satisfaction for the preferred network data units. Providing advertisements to end user devices during downloading provides a effective method of marketing to customers.
